"Our approach is to scan a person wearing the garment, separate the clothing from the person, and then rendering it on top of a new person," says Dr. Gerard Pons-Moll, the project's principal investigator. "This process captures all the detail present in real clothing, including how it moves, which is hard to replicate with simulation."
The product, called ClothCap, uses 4D movies recorded using a scanner with 66 cameras and projectors to take full stock of the person being scanned. This allows the scanner to fully see how clothing drapes on a person's body and where it wrinkles. It also records how a body moves under the clothes and how the garment shifts accordingly. Once this data is analyzed, it's easy to separate the piece of clothing from the original body and use it in virtual try-ons. You can find the full paper on how the tech works in the journal ACM Transactions on Graphics.
